“There were a number of police officers and digital forensics experts there. This took place during the morning and continued until this afternoon. Several servers and computers were seized, but I cannot say exactly how many,” Swedish prosecutor Fredrik Ingblad told Radio Sweden.

Pirate Bay may not be the only target. According to TorrentFreak, other sites related to file sharing such as EZTV, Zoink, and Torrage went down today as well, though it's not yet known if they were also raided.

Founded in 2003, Pirate Bay has been in the legal crosshairs for years, but has managed to stay afloat despite efforts by governments, anti-piracy groups and the music and film industries to close it down. Today's raid comes after a number of recent events have occurred around the service, putting it in the spotlight once again.

The Timeline of Pirate Bay's Recent Troubles

In October, Pirate Bay's co-founder, the Swedish national Gottfrid Svartholm, was found guilty in Denmark and sentenced to 3.5 years in prison. Although the conviction this time was unrelated to file-sharing, it follows a previous 2009 conviction on copyright violations related to the file-sharing service. Svartholm had been convicted on the copyright charges along with his Pirate Bay co-founders, Fredrik Neij, Peter Sunde, and Swedish telecommunitations owner Carl Lundstrom. While all three had been apprehended, Neij went on the lam, however.

Today's raid comes after some of the movie files stolen from Sony Pictures Entertainment in its recent hack became available for download through links at Pirate Bay. It's unknown if the raid and takedown were instigated by the distribution of those Sony files.

Despite the previous convictions, Pirate Bay has managed to forge ahead without its founders, catering to millions of daily users. Although today's raid is not the first—Pirate Bay was also raided in 2006—in 2012 its operators bragged that they had moved their operations to the cloud to make the service virtually impervious to police raids. By hosting their operation from multiple cloud hosting providers located in a number of countries, a single police raid would not be able to disrupt their operation. Or so they thought.

It's unclear how long authorities can keep Pirate Bay down this time before it pops up again.
